This SAE Recommended Practice provides a test procedure for determining revolutions per mile for new truck tires.

This SAE Recommended Practice provides a test procedure for determining revolutions per mile for new truck tires.

The comfort and fatigue of vehicle passengers is a major engineering consideration. Among the many factors involved are vibratory and auditory disturbances. Tires participate, among other elements of the vehicle, in exciting vibrations and noises. Furthermore, tires also may generate forces leading to lateral drift of the vehicle. This SAE Recommended Practice describes the design requirements for equipment to evaluate some of the characteristic excitations of passenger car and light truck tires which may cause disturbance in vehicles. The kinds of excitations treated result from nonuniformities in the structure of the tire and have their effect when a vehicle bearing the tire travels on a smooth road. This document also describes some broad aspects of the use of the equipment and lists precautionary measures that have arisen out of current experience. The intention underlying these recommendations is to establish a standardized measurement for use by the engineering community.

This terminology aims to encompass all terms and definitions pertaining to the road performance of pneumatic tires designed for over-the-highway use, such as passenger car, light truck, truck and bus, and motorcycle tires. Not included are terms specific to the performance of agricultural, aircraft, industrial, and other off-highway tires. However, many terms contained in this document also apply to non-highway tires.

To establish overall performance guidelines, test methods, and minimum performance levels for a TPMS. The system shall visually indicate the tire inflation pressure status. These guidelines include, but are not limited to: a A test methodology for a device which monitors tire inflation, that is located in/on the tire/wheel environment. b Recommended performance guidelines for a TPMS.

This SAE Recommended Practice defines the best known techniques for evaluating peak and locked wheel braking traction. It covers an important phase of tire braking traction, namely, the wet or dry pavement straight ahead conditions. However, this is but a small portion of the whole field of tire traction. As test procedures are established for other phases of this complex study, additional supplementary procedures will be written. A discussion of this entire subject is contained in Appendix B to this recommended practice.
